Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If fly-by-wire flight control systems are used without physical interconnections, then system automation and control precision are improved, but pilot and co-pilot awareness of system behaviors deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the flight control system provides real-time information about its behaviors and states to the pilots through displays and indicators integrated into the control station. This allows pilots to monitor system actions even without physical interconnections, resolving the information loss issue while maintaining automation benefits.
Solution Approach 2:
The patent introduces intermediary display systems and communication interfaces that mediate between the automated flight control system and the pilots. These intermediaries translate system behaviors into visible and understandable information, enabling pilots to awareness of system actions without requiring direct physical connection.
2Device complexity
If passive pilot flight controls with fixed stiffness and damping are used, then device simplicity is improved, but adaptability to different flying conditions deteriorates
Solution Approach 1:
The patent implements dynamic control characteristics where the stiffness and damping of the flight controls can vary based on flight conditions, system states, and pilot inputs. This dynamic adaptation allows the control system to optimize its response for different scenarios while maintaining a relatively simple overall structure by using software-based adjustment rather than complex mechanical reconfiguration.
3Adaptability or versatility
If feedback mechanisms vary force and damping in response to inputs, then system adaptability is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical feedback mechanisms with electronic and software-based systems. Instead of using complex mechanical linkages to provide variable force and damping, the system uses sensors, processors, and actuators to dynamically adjust control characteristics. This substitution reduces mechanical complexity while maintaining or improving adaptability through programmable responses.
